Large-Scale Dynamos Driven by Shear-Flow-Induced Jets

B. Tripathi, A. E. Fraser, P. W. Terry +3

At every scale they occupy, magnetic fields affect various phenomena, including star formation, cosmic ray transport, charged particle acceleration, space weather, transport in pla…

Effect of insulator end cap thickness on time-dependent Hartmann flow in a rotating mirror

Rahul Gaur, Ian G. Abel, Bindesh Tripathi +1

We present a framework for analyzing plasma flow in a rotating mirror. By making a series of physical assumptions, we reduce the magnetohydrodynamic (MHD) equations in a three-dime…

Anisotropic Magnetized Asteroseismic Waves

B. Tripathi, Dhrubaditya Mitra

We solve for waves in a polytropic, stratified plasmas with a spatially varying background magnetic field that points along a horizontal -direction, and with gravity that is dir…

Predicting the Slowing of Stellar Differential Rotation by Instability-Driven Turbulence

B. Tripathi, A. J. Barker, A. E. Fraser +2

Differentially rotating stars and planets transport angular momentum internally due to turbulence at rates that have long been a challenge to predict reliably. We develop a self-co…

Three-Dimensional Shear-Flow Instability Saturation via Stable Modes

B. Tripathi, P. W. Terry, A. E. Fraser +2

Turbulence in three dimensions (D) supports vortex stretching that has long been known to accomplish energy transfer to small scales. Moreover, net energy transfer from large-sc…

Nonlinear mode coupling and energetics of driven magnetized shear-flow turbulence

B. Tripathi, A. E. Fraser, P. W. Terry +3

To comprehensively understand saturation of two-dimensional (D) magnetized Kelvin-Helmholtz-instability-driven turbulence, energy transfer analysis is extended from the traditio…

Near-cancellation of up- and down-gradient momentum transport in forced magnetized shear-flow turbulence

B. Tripathi, A. E. Fraser, P. W. Terry +2

Visco-resistive magnetohydrodynamic turbulence, driven by a two-dimensional unstable shear layer that is maintained by an imposed body force, is examined by decomposing it into dis…

Mechanism for Sequestering Magnetic Energy at Large Scales in Shear-Flow Turbulence

B. Tripathi, A. E. Fraser, P. W. Terry +2

Straining of magnetic fields by large-scale shear flow, generally assumed to lead to intensification and generation of small scales, is re-examined in light of the persistent obser…

Exact analytical solutions in inhomogeneous magnetic fields for linear asteroseismic waves

B. Tripathi, Dhrubaditya Mitra

We solve for waves in an isothermal, stratified medium with a magnetic field that points along a direction perpendicular to that of gravity and varies exponentially in the directio…

Stellar mid-life crisis: subcritical magnetic dynamos of solar-like stars and the breakdown of gyrochronology

Bindesh Tripathi, Dibyendu Nandy, Soumitro Banerjee

Recent observations reveal the surprising breakdown of stellar gyrochronology relations at about the Sun's age hinting that middle-aged, solar-like stars transition to a magnetical…

Origin and Recovery from Grand Solar Minima in a Time Delay Dynamo Model with Magnetic Noise as an Additional Poloidal Source

Bindesh Tripathi, Dibyendu Nandy, Soumitro Banerjee

We explore a reduced Babcock-Leighton (BL) dynamo model based on delay differential equations using numerical bifurcation analysis. This model reveals hysteresis, seen in the recen…
